Which one of the following is not a site of action in human body for the malarial parasite plasmodium?
Explanation
The life cycle of the Plasmodium parasite in humans involves specific target sites. Upon entering the human host via a mosquito bite, sporozoites first migrate to the liver, where they infect hepatocytes to undergo exo-erythrocytic schizogony [1]. Following this, the parasites enter the bloodstream and invade red blood cells (erythrocytes) for asexual multiplication, which is responsible for the clinical symptoms of malaria [6]. In severe cases, particularly with P. falciparum, parasitized red cells can sequester in the microvasculature of the brain, leading to cerebral malaria [5]. While malaria can cause secondary renal pathology or kidney failure due to systemic complications like hemolysis or impaired blood flow, the kidney is not a primary site of action or replication for the Plasmodium parasite itself. The parasite's developmental stages are restricted to the liver and red blood cells.
